>Description:
Fix target_signal_from_host() etc.

The name is wrong for starters.  ``target_signal'' should probably be
``gdb_signal''.  ``from_host'' should be ``from_target_signal''.
After that it needs to be multi-arched and made independent of any
host signal numbering.

Once this is done, the signal enum can probably be moved to
include/gdb so that it is available to embedded stubs.
